Installing the Fishfinder Unit
Selecting a Fishfinder Location
Select a Fishfinder installation location that allows you to
view and operate it easily while operating the vessel. Select
a mounting surface strong enough to support the weight
of the Fishfinder and protect it from excessive vibration or
shock. DO NOT mount the bracket in a location where the
Fishfinder is exposed to extreme temperature conditions.
When installing the mounting bracket, be sure to allow
room to connect and rout the power cable.
Mounting the Bracket Assembly
Tool List (not included)—drill, screwdriver (Phillips or
standard), three #8 pan-head machine bolts with matching
nuts and washers, and a 5/32
"
drill bit; or three #8 pan-
head, self-tapping screws and a 1/16
"
drill bit.
To mount the bracket assembly:
1. Using the tilt mount bracket (Fishfinder 90) or the
swivel base (Fishfinder 140; Fishfinder 90 option)
as a template, mark the location of the three holes
that you use to secure the bracket to the mounting
surface.
2. If securing the base with machine bolts, drill three
5/32" holes at the locations you marked; or, if
securing the base using self-tapping screws, drill
1/16" starter holes at the locations you marked. Drill
starter holes no deeper than half the screw length.
3. Secure the tilt mount bracket or swivel base with
three bolts or screws. DO NOT OVERTIGHTEN.
4. If you are using the swivel mount, place the swivel
mount bracket over the swivel base and secure it
with the short knob.
